'Be it known that LDENNIS C. CIIARMOIS, a cltizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented an Improved Supply and Waste for Bath-Tubs, the same being not claimed, in my application filed July 25, 1910, Serial N 01.57 3,747, maturing in Letters Patent No. 1,001,122, dated August 22, 1911, of which invention the 'followingis av specification.

The invention relates to a device for sup- I plying water into and wasting it from a bath tub or other similar vessel; and the general ob ect ot the nnprovement is to 111-.

troduce the supply through and aroundthe mouth of the waste opening-above a de pressed plug therein, so that the tub can be filled when the waste pipe is closed by the plug, without flushing or washing into the tub any part of the dirt or sediment which may be deposited or accumulated in'the waste pipe and without any splashing orspraying of the inconiing'water.

7 Bath tubes, wash stands, and other similar vessels, are usually made of marble, porcelai'n or some form of enameled Ware, and many kinds of water carry in solution or combination some elements 'or chemicals which discolor the bowl when the same is impinged by a continuous flow or intermittent dropping of water, as by leakage from a defective or slightly open faucet. This and the attendant difticulties may be avoided by depressing the plug seat of the waste pipe and inserting a vertically movable free collar in the mouth thereof and providing an external annular flange on the upper end of the collar and normally resting on the ordinary flange of the waste pipe; and by bringing. the water supply into the tub from under the flange of the collar, and also through the mouth of the collar fromunder the lower end thereof, as set' forth and claimed in said Letters Patent No. 1,001,122.

The present invention involves the use of a disk-like valve connected with the plug by anextensible stem and normally adapted to rest on the flange of the drain pipe or of the free collar when the same is used,

. around the opening of the drain pipe or its collar, and adapted to, be raised by the flow of supply water upward through the mouth of. the drain pipe orthe collar, and thence cnnaiviois, or cannon, eiri o.

' The bath tub 1 is providedwith the aperture 2 in which'is inserted the waste pipe 3. the flange a which is preferably countersunk'and depressed 'below the bottom of the tub as shown. The diameter of. the tub-aperture sec-- preferred form of fittings, and broken away to show the general ar is somewhat larger than the external di-/ ameter of the waste pipe, so that the annular' interval 5 is formed around the pipe;

and the vertical ribs 6 are.preferablynproa vided at intervals, around-thesides hi the waste pipe, which serve to approximately center the same in the tub apertureanfd toinr; sure a free interval on all'sides of thepipev;

The preferably tapered plug'seat "2. is pro vided in the waste pipe,'below which plug:

seat may be provided the internal screw thread 8 for supplemental attachments, not shown, and. above'which plug seat theborc of the waste. pipe issoinewhat enlarged to form the cylindrical recess Q for, the flanged collar 10, andvthe parts areso proportioned and arranged thatthe interior of this ,collar "l the 'wall .of the pipe around the collar re-' -is of largerdiameter. than the larger end of the plug 11, so thatthe plug may pass freely through" the collar to and from the plug the tub, preferably with. the intervening washer 14, and the series of apertures is provided at intervals around the inner side of the flange and extending downward in cess. A series of vertical guide slots 16 is provided in the wall ofthe pipe around the collar recess and a corresponding series of 15 apertures 15 is preferably provided in the adjacent portion of the pipe flange intermel diate the apertures 15. The peripheral rabbet 17, preferably with the inclined shoulder '17, is provided. on the upper face of the pipe flange outside the apertures 15 and 15 .--"-and the internal-shoulder 18 formed at the bottom of the collar recessis preferably beveled'as shown.

The collar 10 normally shields the pipe wall apertures and is made with its external I diameter slightly less than the internal diameter of the pipe recess 9, thus leavinga slight free annularsp'ace bet-ween the collar and the wall of. the recess; and the radial studs, which may be in the form of screws 19 as shown, are provided around the lower end of the collar and areadapted to extend "through and operate in the guide slots'16, l which studs permit a free vertical movement -of the collar in "the recess within thelimits of the slots; but the stops formed by .the upper end of the slot prevent the collar from being entirely withdrawn from the -1;ecess. 40 The flange 20 of the collar is adapted] to normally rest on. the flange 4 of the pipe approximately flush with the bottom of the tub, as shown in Fig. 4,'and the. peripheral rib 21.i s preferably provided on the under side ofthe flange, which 'rib is adapted to normally rest in the peripheral rabbet 17 of the pipe flange and the inner shoulder 21 15 preferably beveled, likethe shoulder of the rabbet, as shown. The lower end 22 of the collar is preferably beveled like the. inclined shoulder 17 a between the pipe recess and the plug seat, and the parts areso arranged that when the collar flange is seated on the pipe flange the lower end of the pipe will be free 0f'the-adjacent pipe shoulder so there is alwaysleft the slight annular interval 23- around the lower end ofthe pipe.

- When necessary or desirable to increase the number and area of the supply openings, the apertures 24 are preferably provided in .the inner part of the collar flange, which apertures, when used, are arched over by. the shields25 which are closed at their outer ends but are open at their inner endto form .6 the inwardlysdirected supply openings 26 tures 24 are preferably located to re ister -with that portion of the drain pipe ange between the apertures 15 and 15 therein, so that when the collar flange is seatedon the pipe flange the apertures in the lower flange will be closed by the upper flange.

The disk-like coveror valve 27 may be employed to normally close the mouth of the drain pipe, and when the shielded apertures 24 are provided in the 'mouth flange of the drain pipe, this cover is sufficiently arched in its middle portion to permit the peripheral edges 27 to rest on the flange outside the shields. The mouth cover is preferably connected with the plug 11 by an extenslble stem, which in the present instance is formed by the axial rod 28 formed or se-' cured on the plug and having the head 29 on Its end; and the axial tube 30 formed or secured on the cover and adapted to operate around the stem rod and its head, and ha.v' ing its lower end reduced in size to engage the lower side of the head of the rod, as a stop, to prevent the complete separation of the cover from the plug.

The supply and waste fitting 31 includes the supply branch 32 and the waste branch 33 with the intervening partition 34, on the upper side of which branches is formed the annular supply chamber 35 in the upper end of which is provided the aperture 36 substantially corresponding to the tub aperture 2; and in the bottom of which chamber, leading to the waste branch, is provided the threaded aperture 37 in which the lower end of the drain pipe is adapted .to be screwed, as shown in Figs. land 5. The upper end of the annular supply chamber is adapted to abut the lower side of the tub around the aperture 2, preferably with the intervening washer 14 and the rim flange 38is preferably provided around the chamber aperture 36 to hold the packing in-proper position. The supply port 39 is provided bet-ween the inlet branch 32 and the annular chamber 35, which port is controlled by the check valve 40.

- The waste branch 32 is connected with the drain pipe 41 and the supply branch 32 is connected with a suitable supply pipe 42 which is preferably branched as at 43 to re ceive hot and cold water, the supply of .which iscontroll-ed bysuitable. valves as 44 and 44 The'small drain port 45 is preferably provided in the partition 34 co'nnecting thebottom of the supply branch with the'waste branch which is adapted to drain the supplybranch and pipe directly into the waste branch, when the valves are closed, and this portis so small as to be negligible with respect to such water as may pass through the same when-the valves are open.

In the operation of the device, the plug 11 being in position as shown in Fig. 1, and one or more of the supply valves open, the water flows from the supply branch into the sup ply chamber by opening the check valve 40 and thence finds its way upward around the annular interval forine'd around the outside .of the drain pipe and thence on upward through the apertures; 15 and 15 in the flange thereof and thence by impinging the flange of thecollar the force of the fiow'of water serves to raise the flanged-collar to the position shown in Fig. 1, whereupon the water flows radially outward in all directions into the tub from under the 'peripheral edge of the-collar flange; the in'- clined shoulder of the edge rib thereof SeIV-- ing to deflect the water downward thus rendering impossible any upward splashing of the same; and also, when the "shielded aper- 'tures are provided in the collar flange, the

water flows radially inward through the supply openings thus formed just above the mouth of the waste opening.

through the collar wall portions of the apertures 15, andalso through the free portions of the guide slots 16, and thence downward through the annular interval 23 between the collar and the drain pipe and thence inward under the free lower end of .the collar and upward through the collar into the tub. And the supply water from under the lower end of the collar, and also from the openings 26 above the mouth of the collar, first fills the cavity between the plug. and the cover, and, holding the plug in place by weight and pressure, then 1111- pinges and raises the cover 27 and flows radially outward from under the peripheral edge thereof; thus preventing any splashing or undue agitation of the incoming supply. It will be understood that it is not essential to use the vertically movable free collar in the mouth of the waste pipe in connection with the disk-like valve for covering and normally closing the mouth of the At the same; time, a lesser amount of water flows inward Waste opening ,-for it is evident that the simplified form of the supply and fwaste illustrated in""IE,ig .f7, the peripheral portion of the disk-valve 27 .Inay' rest directly on the flange Put the waste pipe'fl3 the' plug 11 being located below thesupply apertures 15 in thewall of thewas'te pipe,- the sup?- I ply water will flow inward through; these apertures and thence,,by liftingthe disk valve, will flow upward and radially out: ward from under the peripheral edge thereof without any splashing, in which opera-- tiqnthe connection between the valve and the plug is extended as before described. And finally, for the purpose .of this invention, the flanged collar may itself be considered as part of the waste pipe, for it is" merely an extensible portion thereof.

I claim:
